Abstract

The invention provides a method for retransmitting fast associated control channel (FACCH) signaling and a base station for solving the problems that the retransmission mechanism of the conventional FACCH is only suitable for mobile terminals of specific type and has small application range. The method comprises the following steps that: a frame control unit determines whether the FACCH signaling needs to be retransmitted according to the type of the FACCH signaling and the quality of the FACCH; the frame control unit sets a retransmission mark for expressing whether the retransmission is needed in the FACCH signaling according to the determination result, and transmits the FACCH signaling to a baseband processing unit; and the baseband processing unit receives the FACCH signaling, and determines whether to retransmit the FACCH signaling according to the retransmission mark in the FACCH signaling and whether the mobile terminal has the function of retransmitting the FACCH signaling. According to the technical scheme, the retransmission mechanism of the FACCH can be applied to any mobile terminal, so the success rate of FACCH signaling transmission is improved, and the robustness of a link is improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a method for retransmitting fast associated control channel signaling and a base station. Background technique [0002] In the communication network system, the transmission of signaling is very important. Taking the GSM (Global System for Mobile Communications) network system as an example, in the GSM network system, several logical channels are combined into a specific type for transmitting user data or signaling. Wherein, the FACCH (Fast Associated Control Channel, Fast Associated Control Channel) channel occupies the TCH (Traffic Channel, Traffic Channel) channel to transmit signaling data, specifically, the TCH and FACCH data can be distinguished by the frame stealing flag. For example, in the switching process during a call, it is generally necessary to steal frames through the FACCH to transmit signaling data. Therefore, the success rate of FACCH data tran...
